摘要
开发兼具耐用性和高测量系数(GF)的高温厚膜应变片(TFSG)仍然是一项艰巨的挑战。本研究将聚合物衍生陶瓷技术与填料技术相结合,推出了 SiCNO/In2O3 TFSG。所提出的 TFSG 具有稳定的应变响应和优异的热稳定性,因此可在高达 1100 °C 的温度下使用。值得注意的是,SiCNO/In2O3 TFSG 在 1100 °C 时的电阻漂移极小,仅为 0.31 %/h,而在 1000 °C 时的 GF 值为 10.94,令人印象深刻。这些进步凸显了其在推进系统和工业流程等需要在苛刻热条件下进行精确应变监测的应用中的巨大潜力。
Printing highly sensitive strain gauges with polymer-derived ceramics and In2O3 composites for high-temperature applications
The development of high-temperature thick film strain gauges (TFSGs) that offer both durability and a high gauge factor (GF) remains a formidable challenge. This study integrates polymer-derived ceramic technology with filler techniques to introduce the SiCNO/In2O3 TFSG. The proposed TFSG demonstrates a stable strain response and exceptional thermal stability, enabling its application at temperatures up to 1100 °C. Notably, the SiCNO/In2O3 TFSG exhibits minimal resistance drift of 0.31 %/h at 1100 °C, and an impressive GF of 10.94 at 1000 °C. These advancements underscore its significant potential for applications requiring precise strain monitoring under harsh thermal conditions, such as propulsion systems and industrial processes.
期刊介绍:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
